STL or Qt containers?
...at e.g. QVector uses int as its index, thus limiting 31-bit sizes (even on 64-bit systems). Moreover, it can't even store INT_MAX elements of size larger than 1 byte. E.g. the largest .size() I could have of QVector<float> on x86_64 Linux gcc was 536870907 elements (2²⁹-5), while std::vecto...

How do I safely pass objects, especially STL objects, to and from a DLL?
... datatypes have the same sizes regardless of whether your app is 32-bit or 64-bit. However, since the size of a given datatype is enforced by the compiler, not by any standard (all the standard guarantees is that 1 == sizeof(char) <= sizeof(short) <= sizeof(int) <= sizeof(long) <= sizeof...
Is SHA-1 secure for password storage?
...tions.
About SHA-1 cost:
The elementary cost of SHA-1 is about hashing a 64-byte block. That's how SHA-1 works: data is padded, then split into 64-byte blocks. The cost of processing a single block is about 500 clock cycles on an Intel Core2 system, and that's for a single core. MD5 and MD4 are fa...
